    Yes, that bears out my experience. The optical drive is fine; the enclosure, which is really a Genesys Logic one, is the problem.

    Interesting that another and different Genesys Logic device of mine should give less than stellar performance as well:

    Re: USB CDROM/DVD Device Problems on Ubuntu 10.10

    I am experiencing the same problem on linux mint katya. The ide-usb2 adapter is from SPM (speed dragon multimedia) and uses a nec chipset(ID 0409:0056 NEC Corp.). I have tried all the different jumper positions on the connected drive but discs will not mount regardless of setting. But the command udisks --mount /dev/sr1 from this thread works.

    Code:
    [11970.092170] usb 1-4.6: new high speed USB device using ehci_hcd and address 11
    [11970.188961] scsi7 : usb-storage 1-4.6:1.0
    [11973.711964] scsi 7:0:0:0: CD-ROM PLEXTOR DVDR PX-716A 1.10 PQ: 0 ANSI: 0 CCS
    [11973.851160] sr1: scsi3-mmc drive: 40x/40x writer cd/rw xa/form2 cdda tray
    [11973.851517] sr 7:0:0:0: Attached scsi CD-ROM sr1
    [11973.851760] sr 7:0:0:0: Attached scsi generic sg4 type 5
    The adapter: http://www.speeddragon.com/index.php...uctInfo&Id=106

    Edit: Data DVDs, data CDs and other DVD movies does show up now after maybe waking the drive up the first time with that manual mount command. The discs now show up wihout me doing anything else than placing them in the dvd drive.

    This is an old thread, but since it was one of the top results in google it makes sense to update here. This command line fix solved the issue in 12.04 as well.

    Have a look in /dev. If you have a machine without an internal optical drive, your usb CD/DVD drive will probably appear as sr0. If you have an internal CD/DVD drive, your usb one will probably be sr1. If it doesn't automount when you insert a CD or DVD, simply open a terminal and:

    Code:
    udisks --mount /dev/sr0
    ... or ...

    Code:
    udisks --mount /dev/sr1
    ... depending on whether you have an internal optical drive or not. Your disc will be mounted and a clickable icon will appear on the desktop with a 'disk' label.

    It is not elegant but at least someone in the OP's situation will be able to read CDs and DVDs.
